Exam 4, Set 1

Question 1

general functions of the urinary system

Answer 1

filter blood and create urine as a waste by-product.

Remove Nitrogenous waste

Question 2

ways in which the circulatory and nervous systems are connected to the urinary system

Answer 2

Renal arteries bring blood to kidneys for filtration, Renal veins return filtrated blood to circulatory system. Nervous system controls the whole process.

Question 3

glomerular filtration rate

Answer 3

how much blood passes through the glomeruli each minute.

Question 4

Renal plasma clearance rate

Answer 4

the rate at which a compound is “cleared” from the body, (excreted in the urine)

Question 5

process of mastication

Answer 5

Food in——>Oral muscles and the tongue aid in food manipulation—–> Mechanoreceptors and taste receptors detect food, sending signals to brain stem nuclei—-> saliva production is stimulated—-> Saliva is used to chemically break down food into bolus.

Question 6

bolus

Answer 6

small rounded mass of a substance (Chewed food)

Question 7

purpose of the digestive system

Answer 7

breaks down food into simple nutrients

Question 8

main functions of the stomach

Answer 8

-holds food
-mixes food with acid and enzymes that continue to break the food down into chyme

Question 9

general digestive functions of the small intestine

Answer 9

absorbs nutrients and water from your food

Question 10

general functions of the large intestine

Answer 10

-Absorbing water and electrolytes

-producing and absorbing vitamins

-forming and propelling feces toward the rectum for elimination.

Question 11

purpose of tubular reabsorption

Answer 11

moves solutes and water out of the filtrate and back into your bloodstream

Question 12

the process of tubular secretion

Answer 12

kidneys secrete waste products, such as excess potassium or hydrogen ions, from the bloodstream into the tubular fluid.

Question 13

process of tubular reabsorption, and specifically how substances are reabsorbed.

Answer 13

filtered fluid flows along renal tubule—–> collecting duct—–> tubule cells reabsorb about 99% of the filtered water and many useful solutes

Question 14

the purpose of tubular secretion

Answer 14

remove substances that are not easily filtered (ex: drugs and metabolites)

Question 15

process of micturition

Answer 15

filtration membrane Keeps blood Cells and Large Proteins in the Bloodstream.
Reabsorption Moves Nutrients and Water Back into the Bloodstream.
Waste Ions and Hydrogen Ions Secreted from the Blood complete the Formation of Urine
